I SPECIFICATION forming part. of Letters Patent No. 410,229, datedSeptember 3, 1889.

Application filed June 7, 1889. Serial No, 313,499. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES C. AUGUSTINE, a citizen of the United Statesof America, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Heating-Stoves, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to heating stoves or furnaces of that class inwhich cold air is drawn into the apparatus and directed against theheated surfaces therein and then discharged to be conveyed to anydesired point.

The features of novelty are hereinafter pointed out in the claim.

In the drawings, Figure 1 is a vertical section through the stove orfurnace on a line through the flues of the ring. Fig. 2 is a detailVertical sectional view through the ring and the-parts connectedtherewith on a line through the cold-air ports of said ring. Fig. 3 is aplan view of the ring.

In the drawings, A is the fire-pot, and B the ash-pit, of any desiredform. Upon the top of the fire-pot is secured the ring 0. This is madeof cast metal with a depending flange c for attachment to the fire-pot.The inner cylindrical body portion 0 extends upward in line with thefire-pot and is open at both top and bottom. The upper edge of thisportion forms a bearing-flange upon which is supported the innercylindrical dome D, closed at the top by a cap-piece d. Freecommunication is thus provided through the open cylindrical body portionof the ring between the fire-pot and the dome.

Outside the central part of the ring 0, and concentric therewith, aretwo vertical flanges or rims c 0 the outside one 0 being of less height.These flanges are connected to each other by an approximately-horizontalannular bottom or flange 1, and to the central body part c of the ringby the upper and lower walls of the inwardly-inclined smoke flues orports S, which extend radially outward from the central body part acrossthe intervening open space at the point-s shown in Fig. 3. Thisconstruction and arrangement provide supports for the outer flanges orrims, smoke-flues at a point between the fire-pot and dome, and alsocoldair ports 12 between the smoke-flues S. The flanges c 0 supportvertical concentric cylinders E E. The space between said cylinders isclosed at the top by a plate e, and said space communicates with thefirepot through the flues or ports S. An opening as in the horizontalflange of the ring comm unicates with thesmoke-pipe, and from thisconstruction it will be seen that the course of the products ofcombustion is through the ports S, the annular space 6, and then throughthe port as to the smoke-pipe, and for the purpose of utilizing the heatof the products of combustion as much as possible I provide verticalflue-strips f f (shown'for convenience slightly out of place in Fig. l)in said annular space on each side of the exit-port, so that the draftwill first be upward from the ports S over the top of the flue-sheetsand then down to the exit. The cold air enters the hot-air space 71.from below through the ports 19 p of the ring 0 between the flues S, andduring its passage through this space it is acted upon by the heat fromthe cylindrical dome D, and also from the annular smokespace e,'whic hcompletely surrounds it. An outer inclosing-case is used, preferably,pro vided with exit-openings 0 0, and the air besides being heated inthe space h is acted upon in its passage through the space h.

An important feature of my stove is the 10- cation of the fire-door inrelation to the ring having the flues or ports S, and, as shown, thedoor is positioned below the level of the ring, so that there is noliability of choking the flues by feeding too much coal, nor is thereany chance of the fuel being carelessly thrown into said ports S whenfilling the stove.

It will be noticed that the flange 1 is formed 0 with inclines 10intermediate of the inclined flues S, and by reason of this constructionsoot and dust will not lodge in the annular smoke-space, but will fallinto the inclined flues, and thence into the fire-pot. This flange 5thus serves the twofold purpose of constituting the bottom of thesmoke-space and the means for directing the soot back into thefire-chamber. I prefer to cast the ring all in one piece. The parts maybe bound together Ioo by brace-rods, as '0, Fig. 1.

Having now described my invention, what I claim is- In combination, thefire-pot, the dome, th

inner and outer concentric cylinders, the ring interposed between thefire-pot and the dome and cylinders, said ring being constructed withsheets on either side of the opening, and the feed-door located in thefire-pot below the ring and the ports thereof, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES C. AUGUSTINE.
